Windows Media Player 10 Technical Beta is available for download at microsoft website. Windows Media Player 10 contains a new version of Windows Media Digital Rights Management (DRM) technology, a copy-protection technique formerly code-named Janus, that enhances the software's support for portable devices, says Jonathan Usher, director of the Windows Digital Media division at Microsoft. The DRM technology is intended to combat piracy. However, if a portable device supports Windows Media DRM, users will have greater flexibility in storing and saving music on that device, according to Microsoft.
